The other half concept of Jolla is a good idea. It allows the design of some extra accessories and features so that their design does not interfere too much the design of the phone. It provides also more options for the people who purchase the Jolla phone.

But in the long run, also other alternatives will be needed, for these reasons:

• The sizes of phones and their accessories can vary. When a bigger phone model is launched, for example.
• The stacking of other halves may become complex. If there is more than one half and the phone, putting them together may be problematic. For example, if there is a "tablet half", into which you can insert the phone which is equipped with a "slliding keyboard half". Do you need to remove the keyboard half every time when inserting the phone into the tablet half, or is there space for stacked halves?
• The total price of the phone and its other halves may become a challenge.
• The management and the total volume of the halves may be challenging. The total set which you carry daily may consist of several "halves", which you may drop or forget somewhere. And the total volume of the separate halves may grow bigger than a typical compact camera. You may wish to own the phone + sliding Qwerty keyboard + camera grip, and perhaps a couple of other halves for frequent photographing and for the writing of longish texts.
• There are also other challenges, but llisting them is not the point for this topic.

Please comment by writing your own analysis of what might be needed. You are naturally welcome to critisize this post and its comments.

In this thread we concentrate on the use of the phone when it is equipped with a sliding Qwerty keyboard and/or camera grip, and perhaps some related accessories. But before writing a detailed comment about a new feature which might be out of the scope of the "phone + keyboard + camera grip" concept, please first suggest whether your new feature can be discussed in this thread. Or create another thread for the new feature of yours.
